Gas-burner



UNITED STATES PATENT OFFICE.

JAMES GILFILLAN, OF HARTFORD, CONNECTICUT.

GAS-BURNER.

Specication of Letters Patent No. 24,932, dated August 2. 1859.

To all whom it' may concern:

Be it known that I, Jaulas GILFILLAX. olf Hartford, county of Hartford,and State of Connecticut. have invented certain new and usefulImprovements in Gas-Burners; I do hereby declare that the. same isdescribed and represented in the following :specification and drawings;and to enable others .skilled in the art to make and use my improve-mentI will proceed to describe its construction and operation7 referring tothe drawings, in which the Same letters indicate like parts in each ofthe figures..

The. nature of this improvement consists` in its peculiar' constructionand adaptation for an automatic regulating burner.

In the accompanying drawings Figure 1, is a section view. Showing themanner of its construction. Fig. 2, shows the manner of applying twoburners in the place ot' one (as shown in Fig. l) concentrating twoflames into one.

a is a burner nipple, now in common use.

b, is a tube made in two'parts each having a collar and a screw wz, bywhich the two are fastened together, and into the upper end ol" whichthe. burner nipple a, is secured` n, is the body of the burner.

7, is a nipple secured in the lower end by a screw and in most cases itwill be entirely unnecessary. as the. .screw may be cut l directly uponthe lower part ot' the body of' the burner. L*aid nipple. or screw is tocure the burner in place. to the chandelier or bracket.

i, is the valise-seat. or opening through which the gasl is admittedinto the chamber y. thence into the burner tube through the holes /1t orinto the side tubes o. instead o't the tube.

j. isa valve on the lower end ot the tube c. is a compression chamber.fitted onto the. tube between the flanges d.

f. is a channel of `sutlicient depth to receive the full deplli olf thcrim ot' the chambta c.

and l c. is a cap fitted onto the top of the body of the burner a.

I have thus described the construction ot' my improvement. To show theoperation thereof. the burner is first secured in place where it desiredto be used. the cap c is removed and the channel f', is filled withmercury, and the cap again replaced. when the gas may be let on andlighted in the uaual manner. Now it will be clearly seen that it is onlynecessary to select a nipple, tested to burn. or give the requiredflame, or light. or a given tpiantity of' gas per hour, to secureagainst a greater amount thereof, passing through the burner. by theincrease, or variation ol the pressure of gas in the pipes. or in otherwords, to secure a uniform pres'sure and flame. ecause asthe pressure inthe pipes increase."y the pressure lifts the chamber c, thereby closingor opening the valve j, more or less according to the amount of pressurefrom the gas. The mercury meanwhile serving to prevent the escape ofgais. and allow of' a free action of the chamber c, up or down therein.

Thus I am enahletfl to produce a self regulating burner. giving arequired flame or light as may be required by a given size nipple. Ibelieve I have thus.I shown and described the operation and advantagederived by my improvement over others now in use.

I clain'rw The improvement in gas burners herein described consisting ola central exit tube supplied with apertures surrounded by the gaschamber having its discharge regulated by the mercury cap the upper endof said pipe being Jfurnished with a nozzle or jetburner the wholeconstructed and operating l"ubstantially as set forth.
